Abstract
The reaction of K-3[Cu(CN)(4)], Me3SnCl and 4-methylpyrimidine (mpym) at room temperature affords the 3D-octameric (a) (3) [Cu-8(CN)(8)(mpym)(4)], I, in water/acetonitrile and the 3D-host-guest (a) (3) [Cu-8(CN)(8)(mpym)(4) dioxane], II. The X-ray single crystal diffraction of I reveals the formation of homometallic octameric building blocks consisting of three fused 11 membered rings. The 3D-network structure of the supramolecular coordination polymer (SCP), I, consists of two crossing sets of parallel corrugated interpenetrating CuCN chains, which are connected by mpym, hydrogen bonds, pi-pi stacking and cuprophilic interactions. Species II is isostructural with I as indicated by X-ray powder diffraction and spectroscopic measurements.
